Glock 29/30 Molle/Pals compatible Holster

I'm looking for a holster for my Glock 29 that has:
a) an extra mag pouch attached to it, and
b) is attachable to my pack (or me via my belt) with a Molle/Pals style attachment. (Doesn't have to be brand name military issue Pals approved, just has to work with it and not fall off under moderately heavy use).

I have been looking for some time and have not been able to find something that fits this bill, so I am widening my search to include more minds than my own. Thanks.
